摘要
文章研究了块H-矩阵的重要子类块α2-对角占优矩阵的判定问题,利用块H-矩阵的块α2-对角占优性质,给出了块α2-对角占优矩阵(块H-矩阵)新的仅依赖于矩阵元素的简捷判据。
The paper studies the determination of important subclass of block α2-diagonally dominant matrices of the block-matrix,using block α2-diagonally dominant properties of the block H-matrix,and gives a new simple criterion of block α2-diagonally dominant matrix(block H-matrix) which only depends on the matrix elements.
